@ -1870,7 +1870,7 @@ There are some more advanced barrier functions:
These are for use with atomic RMW functions that do not imply memory
barriers, but where the code needs a memory barrier. Examples for atomic
RMW functions that do not imply are memory barrier are e.g. add,
RMW functions that do not imply a memory barrier are e.g. add,

but not atomic_read or atomic_set. A common example where a memory
barrier may be required is when atomic ops are used for reference
